What happened: Chase Burns credited an unorthodox training tweak for his fastball velocity gain. His heater has touched 100 mph at the bottom of the zone this season.
Why it matters: Added velocity widens the margin for his secondary arsenal to play off the heater. Consistent triple-digit readings change how lineups prepare for his starts down the stretch.
By the numbers: Fastball touched 100 mph at bottom of zone; held opponents to two or fewer runs across nine straight starts in June.
What to watch: His remaining September starts will show whether the added velocity holds under workload.
